Doesn’t ChatGPT use beam search?

1 comments

Almost certainly not.

It's absolutely just sampling with temperature or top_p/k, etc. Beam searches would be very expensive, I can't see them doing that for chatgpt which appears to be their "consumer product" and often has lower quality results compared to the api.

The old legacy had a "best_of" option but that doesn't exist in the new api.
